An eXpert AFB Smear?

An eXpert AFB smear?

The development, evaluation, and World Health Organization (WHO) endorsement of the Xpert MTB/RIF automated real-time polymerase chain reaction (PCR) assay has generated considerable excitement as a revolutionary diagnostic test for tuberculosis. However, one of its limitations is the inability to determine which patients with pulmonary tuberculosis have sputum positive for acid-fast bacilli (A...

Risk factors in patients with AFB smear-positive sputum who receive inappropriate antituberculous treatment

BACKGROUND Acid-fast bacilli (AFB) smear-positive sputum is usually an initial clue in the diagnosis of pulmonary tuberculosis (TB); however, the test is not disease-specific. Nontuberculous mycobacterium-related colonization or lung disease often has AFB smear-positive sputum results, and physicians may prescribe unnecessary antituberculous drugs for these patients. The aim of this study was t...

Appendix C AFB Interface

In this appendix, we describe an initial version of the AFB interface. We specify it as a system-call oriented interface between the operating system and the application programs. We refer to pages in a virtual memory address space by symbolic names like a i and b, although the actual interface will require the use of each page's actual virtual memory address. SAPPs are assigned unique identifi...

Comparison of AFB Smear Microscopy and Culture from Specimens Received for the Diagnosis of Extra Pulmonary Tuberculosis

Objectives: This study was undertaken to see the role of AFB microscopy and culture for the diagnosis of extra pulmonary tuberculosis. Design and Setting: This descriptive study was carried out at PMRC TB Research Centre King Edward Medical University/Mayo Hospital Lahore. Subject and Methods: Symptomatic suspects of extra-pulmonary TB were asked to submit their respective samples for AFB smear...
